A Clinical Study of Association Between Postoperative Dyslipidemia and Organ Rejection in Transplant Patients

Abnormal lipid metabolism is a common complication after organ transplantation, with pathological changes in lipid parameters occurring in approximately 60-80% of cardiac transplant recipients receiving triple immunotherapy with cyclosporine, imid azathioprine, and methylprednisolone. With the significant increase in long-term survival and increasing age of transplant patients, atherosclerotic cardiovascular diseases, such as those caused by dyslipidemia, have become a major cause of transplant organ failure and recipient death. However, the causes of dyslipidemia after organ transplantation, as well as the effects and mechanisms of dyslipidemia on transplant rejection, are unknown. Previous studies have found that 1. increased lipid levels occur in recipients after heart transplantation; 2. during rejection, hepatic PCSK9 expression is increased in recipients; 3. a high-fat environment increases the immunoreactivity of human peripheral blood lymphocytes. It is suggested that PCSK9-lipid disorder-immune cell interactions may be associated with the development of transplant rejection. In this project, we propose to (1) establish a long-term follow-up system for postoperative cardiac transplantation patients in our department to track the characteristics of lipid changes in transplantation patients, to clarify the link between dyslipidemia and rejection, and to provide a strong evidence-based medical basis for the management of lipids during the perioperative period and in th…
